Abstract
Barium titanate–cobalt ferrite composite powders prepared by sol–gel method and by mixing of precursors were characterized by Raman spectroscopy, scanning electron microscopy and Rietveld refinement of XRD data. Ba vacancies and BaTiO3–CoFe2O4 interfacial stress were associated to lowering of tetragonal distortion in the ferroelectric structure. Raman spectroscopy suggested the encapsulation of ferrite inside clusters of particles in the sol–gel composite.
